1. (a) The owner shall ensure that an operation and maintenance manual of the water system is on file at the system, and the owner shall submit said manual to the department as part of or prior to the notification required by Env-Dw 406.28(a).

2. (b) The manual, electronic or paper, required by (a) above, shall:

   1. (1) Always be available on-site at the water system and, if paper, be bound; and

   2. (2) Include the following:

      1. a. A schematic drawing of the treatment process, which shall identify each unit of the treatment equipment by:

         1. 1. Type;
         2. 2. Size;
         3. 3. Model number; and
         4. 4. Any appurtenances;
      2. b. An original or a photocopy of the description of the treatment equipment from the manufacturer’s catalogue;

      3. c. A separate schematic drawing of the treatment process in the normal production configuration, which shall include:

         1. 1. A written description of the process, which shall reference the schematic drawing and show flow direction; and
         2. 2. The approximate expected values, settings, or feed rates for pumps, gauges, gate valves, and controllers in the production mode;

      4. d. A separate schematic drawing of the treatment process in the normal backwash or regeneration configuration, which shall include:

         1. 1. A written description which references the schematic drawing, showing the backwash or regeneration process functions which shall include:

         2. i. The flow rate of backwash or regeneration and its temperature dependency where applicable;

            ii. The duration of backwash or regeneration; and

            iii. The frequency of anticipated backwashes or regenerations;

         3. 2. The approximate expected values, settings, or feed rates for pumps, gauges, isolation valves, and controllers in the backwash mode; and
         4. 3. The backwash disposal location and a copy of the backwash waste discharge registration issued by the department;
      5. e. Recommended short- and long-term maintenance schedules for each piece of equipment;
      6. f. A description of common operational problems and proposed corrective operator responses;

      7. g. A description of how the operator can maximize the efficiency of the treatment process relative to:

         1. 1. Energy use;
         2. 2. Chemical use;
         3. 3. Maximizing the net treated water production volume; and
         4. 4. Minimizing the volume of waste and by-products produced; and
      8. h. A blank copy of the compliance and oversight operational form that is required by Env-Dw 503 to be submitted to the department when a water system performs treatment.
